Multiple myeloma diet. Is there a diet which improves the quality of life of people with Multiple myeloma?

There is currently no specific "Multiple myeloma diet" proven to cure the disease or stop its progression, but balanced nutrition is essential to manage treatment side effects and improve quality of life. Patients with Multiple myeloma should prioritize a diet that supports kidney function, bone health, and immune resilience while consulting their oncology team before starting any new dietary regimen.

What nutritional goals are important for Multiple myeloma patients?

Because Multiple myeloma often impacts bone density and renal function, dietary strategies focus on symptom management. High protein intake is often encouraged to combat muscle wasting, while adequate hydration is critical to protect the kidneys from the high levels of monoclonal proteins (M-proteins) produced by Multiple myeloma cells. There is no high-level clinical evidence supporting restrictive protocols like ketogenic or extreme elimination diets for Multiple myeloma; in fact, these may lead to dangerous nutrient deficiencies during intensive chemotherapy or immunotherapy.

Which foods and supplements should be managed?

While no single food treats Multiple myeloma, the following guidelines are widely recommended by oncology dietitians:

• Hydration: Aim for 2–3 liters of fluid daily to help the kidneys filter excess proteins.


• Bone Health: Ensure adequate calcium and Vitamin D intake, but only under physician supervision, as some patients may have hypercalcemia.


• Food Safety: If you are immunocompromised due to Multiple myeloma treatments, follow a low-microbial diet (avoiding raw fish, unpasteurized dairy, and undercooked meats).


• Supplements: Always discuss supplements like curcumin, green tea extract, or high-dose antioxidants with your doctor, as they can interfere with the metabolism of drugs like bortezomib or lenalidomide.

How does diet interact with Multiple myeloma medications?

Some medications for Multiple myeloma have specific dietary requirements. For example, certain drugs may cause nausea or alter taste, requiring small, frequent meals rather than large ones. Additionally, steroids used in Multiple myeloma protocols can cause blood sugar spikes, necessitating a reduction in refined sugars and simple carbohydrates to maintain glycemic control.
